Description of Research
Stem/Progenitor Cells in Development and Disease
How do internal organs achieve their remarkable structures? What determines the size of organs? How are stem cells regulated in adult solid organs? What cells give rise to cancer? During mammalian organogenesis, stem/progenitor cells and their derivatives undergo carefully controlled division, differentiation, and morphogenesis to generate complex functioning three-dimensional structures. Our laboratory uses the tools of developmental biology to address problems relevant to development, regenerative medicine and cancer. In particular, we use the mouse as a model system to genetically tag specific cellular lineages or to alter the function of important signaling pathways. The focus is on stem cells and progenitor cells in the vertebrate liver and pancreas, essential organs with great clinical importance and a rich history in developmental biology. Our long-term goal is to understand in detail how these different cell types behave during development, organ regeneration, and carcinogenesis. We hope to exploit insights gained from these studies to develop new approaches to cancer therapy and bioengineering.
